Basis of Presentation	BASIS OF PRESENTATION: The accompanying Unaudited Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for future periods. The Consolidated Balance Sheet at December 31, 2018 has been derived from the Audited Consolidated Financial Statements at that date but does not include all the notes required by generally accepted accounting principles for complete financial statements. For further information, refer to the Consolidated Financial Statements and related notes for the year ended December 31, 2018 included in CNX Resources Corporation's ("CNX," "CNX Resources," the "Company," "we," "us," or "our") Annual Report on Form 10-K as filed with the Securities and Exchange Commission (SEC) on February 7, 2019. Certain amounts in prior periods have been reclassified to conform to the current period presentation. The Consolidated Balance Sheet at September 30, 2019 reflects the full consolidation of CNX Gathering LLC's assets and liabilities as a result of the acquisition by CNX Gas Company LLC ("CNX Gas"), an indirect wholly owned subsidiary of CNX, of NBL Midstream, LLC's ("Noble") 50%

Earnings Per Share

Earnings Per Share	9 Months Ended
	Sep. 30, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Earnings Per Share	EARNINGS PER SHARE: Basic earnings per share is computed by dividing net income attributable to CNX shareholders by the weighted average shares outstanding during the reporting period. Diluted earnings per share are computed similarly to basic earnings per share, except that the weighted average shares outstanding are increased to include additional shares from stock options, performance stock options, restricted stock units and performance share units, if dilutive. The number of additional shares is calculated by assuming that outstanding stock options and performance share options were exercised, that outstanding restricted stock units and performance share units were released, and that the proceeds from such activities were used to acquire shares of common stock at the average market price during the reporting period. CNX Midstream Partners LP's ("CNXM") dilutive units did not have a material impact on the Company's earnings per share calculations for the three or nine months ended September 30, 2019 , the three months ended September 30, 2018 , or the period from January 3, 2018 through September 30, 2018 . The table below sets forth the share-based awards that have been excluded from the computation of diluted earnings per share because their effect would be antidilutive: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2019 2018 2019 2018 Anti-dilutive Options 2,035,273 2,288,274 2,035,273 2,288,274 Anti-dilutive Restricted Stock Units 814,183 — 813,266 55,936 Anti-dilutive Performance Share Units — 157,120 — 157,120 Anti-dilutive Performance Stock Options 927,268 927,268 927,268 927,268 3,776,724 3,372,662 3,775,807 3,428,598 The table below sets forth the share-based awards that have been exercised or released: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2019 2018 2019 2018 Options 6,953 18,546 27,794 245,847 Restricted Stock Units 28,769 184,176 1,002,003 362,573 Performance Share Units — 192,926 342,882 550,523 35,722 395,648 1,372,679 1,158,943 Pursuant to the terms of the change in control severance agreements of certain employees and CNX officers, outstanding equity awards held by such employees vest upon a stockholder (or stockholder group) becoming the beneficial owner of more than 25% of the Company's outstanding common stock. During the nine months ended September 30, 2019 , Southeastern Asset Management, Inc. and its affiliates ("SEAM") acquired shares of CNX's common stock in the open market which resulted in SEAM's aggregate share ownership exceeding more than 25% of CNX's common stock outstanding. This transaction, as such, constituted a change in control event under the severance agreements, resulting in the accelerated vesting of 473,126 restricted stock units and 903,100 performance share units held by the aforementioned employees that were issued prior to 2019. Those affected employees and officers each consented to waive the change in control vesting provision included in the change in control severance agreements with respect to their 2019 restricted stock unit and performance share unit awards. The accelerated vesting resulted in $19,654 of additional long-term equity-based compensation expense for the nine months ended September 30, 2019 , and is included in Selling, General, and Administrative Costs in the Consolidated Statements of Income. The performance share unit awards that vested continue to be subject to the attainment of performance goals as determined by the Compensation Committee of CNX's Board of Directors after the end of the applicable performance period. The computations for basic and diluted earnings per share are as follows: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2019 2018 2019 2018 Net Income $ 143,960 $ 146,756 $ 272,004 $ 753,696 Less: Net Income Attributable to Non-Controlling Interest 28,422 21,727 81,325 59,090 Net Income Attributable to CNX Resources Shareholders $ 115,538 $ 125,029 $ 190,679 $ 694,606 Weighted-average Shares of Common Stock Outstanding 187,448,749 210,238,509 188,012,044 216,010,561 Effect of Diluted Shares 982,210 2,469,573 1,548,899 2,288,301 Weighted-average Diluted Shares of Common Stock Outstanding 188,430,959 212,708,082 189,560,943 218,298,862 Earnings per Share: Basic $ 0.62 $ 0.59 $ 1.01 $ 3.22 Diluted $ 0.61 $ 0.59 $ 1.01 $ 3.18

Revenue From Contracts With Customers	REVENUE FROM CONTRACTS WITH CUSTOMERS: Revenues are recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. The Company has elected to exclude all taxes from the measurement of transaction price. For natural gas, NGLs and oil, and purchased gas revenue, the Company generally considers the delivery of each unit (MMBtu or Bbl) to be a separate performance obligation that is satisfied upon delivery. Payment terms for these contracts typically require payment within 25 days of the end of the calendar month in which the hydrocarbons are delivered. A significant number of these contracts contain variable consideration because the payment terms refer to market prices at future delivery dates. In these situations, the Company has not identified a standalone selling price because the terms of the variable payments relate specifically to the Company’s efforts to satisfy the performance obligations. A portion of the contracts contain fixed consideration (i.e. fixed price contracts or contracts with a fixed differential to NYMEX or index prices). The fixed consideration is allocated to each performance obligation on a relative standalone selling price basis, which requires judgment from management. For these contracts, the Company generally concludes that the fixed price or fixed differentials in the contracts are representative of the standalone selling price. Revenue associated with natural gas, NGLs and oil as presented on the accompanying Consolidated Statements of Income represent the Company’s share of revenues net of royalties and excluding revenue interests owned by others. When selling natural gas, NGLs and oil on behalf of royalty owners or working interest owners, the Company is acting as an agent and thus reports the revenue on a net basis. Midstream revenue consists of revenues generated from natural gas gathering activities. The gas gathering services are interruptible in nature and include charges for the volume of gas actually gathered and do not guarantee access to the system. Volumetric based fees are based on actual volumes gathered. The Company generally considers the interruptible gathering of each unit (MMBtu) of natural gas as a separate performance obligation. Payment terms for these contracts typically require payment within 25 days of the end of the calendar month in which the hydrocarbons are gathered. Disaggregation of Revenue The following table is a disaggregation of revenue by major source: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2019 2018 2019 2018 Revenue from Contracts with Customers Natural Gas Revenue $ 245,815 $ 293,864 $ 966,574 $ 930,505 NGLs Revenue 18,305 46,663 72,095 137,104 Condensate Revenue 839 3,426 4,846 14,925 Oil Revenue 92 759 347 2,317 Total Natural Gas, NGLs and Oil Revenue 265,051 344,712 1,043,862 1,084,851 Purchased Gas Revenue 29,192 10,560 64,181 38,546 Midstream Revenue 18,525 19,946 55,863 69,684 Other Sources of Revenue and Other Operating Income Gain on Commodity Derivative Instruments 213,913 18,005 240,118 78,752 Other Operating Income 3,316 3,903 9,436 23,146 Total Revenue and Other Operating Income $ 529,997 $ 397,126 $ 1,413,460 $ 1,294,979 The disaggregated revenue corresponds with the Company’s segment reporting found in Note 17 - Segment Information. Contract Balances CNX invoices its customers once a performance obligation has been satisfied, at which point payment is unconditional. Accordingly, CNX's contracts with customers do not give rise to contract assets or liabilities under Accounting Standards Codification (ASC) 606. The Company has no contract assets recognized from the costs to obtain or fulfill a contract with a customer. The opening and closing balances of the Company’s receivables related to contracts with customers were $ 252,424 and $ 96,997 , respectively, as of September 30, 2019 . Transaction Price Allocated to Remaining Performance Obligations ASC 606 requires that the Company disclose the aggregate amount of transaction price that is allocated to performance obligations that have not yet been satisfied. However, the guidance provides certain practical expedients that limit this requirement, including when variable consideration is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a distinct good or service that forms part of a series. A significant portion of CNX's natural gas, NGLs and oil and purchased gas revenue is short-term in nature with a contract term of one year or less. For those contracts, CNX has utilized the practical expedient in ASC 606-10-50-14 exempting the Company from disclosure of the transaction price allocated to remaining performance obligations if the performance obligation is part of a contract that has an original expected duration of one year or less. For revenue associated with contract terms greater than one year, a significant portion of the consideration in those contracts is variable in nature and the Company allocates the variable consideration in its contract entirely to each specific performance obligation to which it relates. Therefore, any remaining variable consideration in the transaction price is allocated entirely to wholly unsatisfied performance obligations. As such, the Company has not disclosed the value of unsatisfied performance obligations pursuant to the practical expedient. For revenue associated with contract terms greater than one year with a fixed price component, the aggregate amount of the transaction price allocated to remaining performance obligations was $ 155,567 as of September 30, 2019 . The Company expects to recognize net revenue of $ 43,538 in the next 12 months and $ 47,076 over the following 12 months, with the remainder recognized thereafter. For revenue associated with our midstream contracts, which also have terms greater than one year, the interruptible gathering of each unit of natural gas represents a separate performance obligation; therefore, future volumes are wholly unsatisfied, and disclosure of the transaction price allocated to remaining performance obligations is not required. Prior-Period Performance Obligations CNX records revenue in the month production is delivered to the purchaser. However, settlement statements for certain natural gas and NGL revenue may not be received for 30 to 90 days after the date production is delivered, and as a result, the Company is required to estimate the amount of production delivered to the purchaser and the price that will be received for the sale of the product. CNX records the differences between the estimate and the actual amount received in the month that payment is received from the purchaser. The Company has existing internal controls for its revenue estimation process and the related accruals, and any identified differences between its revenue estimates and the actual revenue received historically have not been significant. For the three and nine months ended September 30, 2019 and 2018, revenue recognized in the current reporting period related to performance obligations satisfied in a prior reporting period was not material.

Business Combinations [Abstract]
Acquisitions And Dispositions	ACQUISITIONS AND DISPOSITIONS: On August 31, 2018, CNX closed on the sale of substantially all of its Ohio Utica Joint Venture Assets in the wet gas Utica Shale areas of Belmont, Guernsey, Harrison, and Noble Counties, which included approximately 26,000 net undeveloped acres. The net cash proceeds of $381,214 are included in Proceeds from Asset Sales in the Consolidated Statements of Cash Flows and the net gain on the transaction of $130,849 is included in the Gain on Asset Sales and Abandonments in the Consolidated Statements of Income. On May 2, 2018, CNX closed on an Asset Exchange Agreement (the “AEA”) with HG Energy II Appalachia, LLC (“HG Energy”), pursuant to which, among other things, HG Energy (i) paid to CNX approximately $7,000 and (ii) assigned to CNX certain undeveloped Marcellus and Utica acreage in Southwest Pennsylvania, in exchange for CNX (x) assigning its interest in certain non-core midstream assets and surface acreage to HG Energy and (y) releasing certain HG Energy oil and gas acreage from dedication under a gathering agreement that is partially held, indirectly, by CNX. In connection with the transaction, CNX also agreed to certain transactions with CNXM, including the amendment of the existing gas gathering agreement between CNX and CNXM to increase the existing well commitment by an additional forty wells. The net gain on the sale was $286 and is included in the Gain on Asset Sales and Abandonments line of the Consolidated Statements of Income. As a result of the AEA, CNX determined that the carrying value of a portion of the customer relationship intangible assets that were acquired in connection with the Midstream Acquisition discussed below (see also Note 8 - Goodwill and Other Intangible Assets) exceeded their fair value, and recognized an impairment of approximately $18,650 which is included in the Impairment of Other Intangible Assets line of the Consolidated Statements of Income. On March 30, 2018, CNX Gas completed the sale of substantially all of its shallow oil and gas assets and certain Coalbed Methane (CBM) assets in Pennsylvania and West Virginia for $89,296 in cash consideration. In connection with the sale, the buyer assumed approximately $196,514 of asset retirement obligations. The net gain on the sale was $4,432 and is included in Gain on Asset Sales and Abandonments in the Consolidated Statements of Income for the nine months ended September 30, 2018 . On December 14, 2017, CNX Gas entered into a purchase agreement with Noble, pursuant to which CNX Gas acquired Noble’s 50% membership interest in CONE Gathering LLC ("CNX Gathering"), for a cash purchase price of $305,000 and the mutual release of all outstanding claims (the "Midstream Acquisition"). CNX Gathering owns a 100% membership interest in CONE Midstream GP LLC (the "general partner"), which is the general partner of CONE Midstream Partners LP ("CNXM" or the "Partnership"), which is a publicly traded master limited partnership formed in May 2014 by CNX Gas and Noble. In conjunction with the Midstream Acquisition, which closed on January 3, 2018, the general partner, the Partnership and CONE Gathering LLC changed their names to CNX Midstream GP LLC, CNX Midstream Partners LP, and CNX Gathering LLC, respectively. Prior to the Midstream Acquisition, the Company accounted for its 50% interest in CNX Gathering as an equity method investment as the Company had the ability to exercise significant influence, but not control, over the operating and financial policies of the midstream operations. In conjunction with the Midstream Acquisition, the Company obtained a controlling interest in CNX Gathering and, through CNX Gathering's ownership of the general partner, control over the Partnership. Accordingly, the Midstream Acquisition has been accounted for as a business combination using the acquisition method of accounting pursuant to ASC Topic 805, Business Combinations , or ASC 805. ASC 805 requires that, in circumstances where a business combination is achieved in stages (or step acquisition), previously held equity interests are remeasured at fair value and any difference between the fair value and the carrying value of the equity interest held be recognized as a gain or loss on the statement of income. The fair value assigned to the previously held equity interest in CNX Gathering and CNXM for purposes of calculating the gain or loss was $799,033 and was determined using the income approach, based on a discounted cash flow methodology. The resulting gain on remeasurement to fair value of the previously held equity interest in CNX Gathering and CNXM of $623,663 is included in Gain on Previously Held Equity Interest in the Consolidated Statements of Income. The fair value of the previously held equity interests was based on inputs that are not observable in the market and therefore represent Level 3 inputs (See Note 15 - Fair Value of Financial Instruments). The fair value was measured using valuation techniques that convert future cash flows into a single discounted amount. Significant inputs to the valuation included estimates of: (i) gathering volumes; (ii) future operating costs; and (iii) a market-based weighted average cost of capital. These inputs required significant judgments and estimates by management. The fair value of midstream facilities and equipment, generally consisting of pipeline systems and compression stations, were estimated using the cost approach. Significant unobservable inputs in the valuation include management's assumptions about the replacement costs for similar assets, the relative age of the acquired assets and any potential economic or functional obsolescence associated with the acquired assets. As a result, the fair value estimates of the midstream facilities and equipment represents a Level 3 fair value measurement. As part of the purchase price allocation, the Company identified intangible assets for customer relationships with third-party customers. The fair value of the identified intangible assets was determined using the income approach, which requires a forecast of the expected future cash flows generated and an estimated market-based weighted average cost of capital. Significant unobservable inputs in the valuation include future revenue estimates, future cost assumptions, and estimated customer retention rates. As a result, the fair value estimate of the identified intangible assets represents a Level 3 fair value measurement. The noncontrolling interest in the acquired business is comprised of the limited partner units in CNXM, which were not acquired by the Company. The CNXM limited partner units are actively traded on the New York Stock Exchange and were valued based on observable market prices as of the transaction date and therefore represent a Level 1 fair value measurement. Allocation of Purchase Price (Midstream Acquisition) The following table summarizes the purchase price and the amounts of identified assets acquired and liabilities assumed based on the fair value as of January 3, 2018, with any excess of the purchase price over the fair value of the identified net assets acquired recorded as goodwill. The purchase price allocation was finalized as of December 31, 2018. Fair Value of Consideration Transferred: Amount Cash Consideration $ 305,000 CNX Gathering Cash on Hand at January 3, 2018 Distributed to Noble 2,620 Fair Value of Previously Held Equity Interest 799,033 Total Estimated Fair Value of Consideration Transferred $ 1,106,653 The following is a summary of the fair values of the net assets acquired: Fair Value of Assets Acquired: Amount Cash and Cash Equivalents $ 8,348 Accounts and Notes Receivable 21,199 Prepaid Expense 2,006 Other Current Assets 163 Property, Plant and Equipment, Net 1,043,340 Intangible Assets 128,781 Other 593 Total Assets Acquired 1,204,430 Fair Value of Liabilities Assumed: Accounts Payable 26,059 CNXM Revolving Credit Facility 149,500 Total Liabilities Assumed 175,559 Total Identifiable Net Assets 1,028,871 Fair Value of Noncontrolling Interest in CNXM (718,577 ) Goodwill 796,359 Net Assets Acquired $ 1,106,653 Post-Acquisition Operating Results (Midstream Acquisition) The Midstream Acquisition contributed the following to the Company's Midstream segment: Three Months Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Midstream Revenue $ 74,261 $ 61,372 $ 225,280 $ 186,875 Earnings Before Income Tax $ 41,741 $ 31,173 $ 118,739 $ 94,502

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES: The effective tax rates for the three and nine months ended September 30, 2019 were 25.4% and 22.3% , respectively. The effective tax rate for the nine months ended September 30, 2019 differs from the U.S. federal statutory rate of 21% primarily due to the impact of noncontrolling interest, equity compensation and state income taxes. The effective tax rates for the three and nine months ended September 30, 2018 were 27.9% and 24.1% , respectively. The effective rate for the nine months ended September 30, 2018 differs from the U.S. federal statutory rate of 21% primarily due to increases for both state income taxes and state valuation allowances, offset by the benefit derived from the filing of a Federal 10-year net operating loss (“NOL”) carryback as well as non-controlling interest. On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act (the "Act") which, among other things, lowered the U.S. Federal corporate income tax rate from 35% to 21%, repealed the corporate alternative minimum tax ("AMT"), and provided for a refund of previously accrued corporate AMT credits. As of December 31, 2018, the Company reclassified $102,482 from Deferred Income Taxes to Recoverable Income Taxes in the Consolidated Balance Sheets in anticipation of the AMT refund that is also included in the Recoverable Income Taxes line of the Consolidated Statements of Cash Flows in the nine months ended September 30, 2019 . The total amount of uncertain tax positions at each of September 30, 2019 and December 31, 2018 was $31,516 . If these uncertain tax positions were recognized, approximately $31,516 would affect CNX's effective tax rate. There were no changes in unrecognized tax benefits during the three and nine months ended September 30, 2019 . CNX recognizes accrued interest related to uncertain tax positions in interest expense. As of September 30, 2019 and December 31, 2018 , CNX had no accrued liabilities for interest related to uncertain tax positions. CNX recognizes penalties accrued related to uncertain tax positions in its income tax expense. As of September 30, 2019 and December 31, 2018 , CNX had no accrued liabilities for tax penalties related to uncertain tax positions.

Goodwill and Other Intangible Assets	GOODWILL AND OTHER INTANGIBLE ASSETS: In connection with the Midstream Acquisition that closed on January 3, 2018 (See Note 5 - Acquisitions and Dispositions for more information), CNX recorded $796,359 of goodwill and $128,781 of other intangible assets which are comprised of customer relationships. All goodwill is attributed to the Midstream reportable segment. The carrying amount and accumulated amortization of other intangible assets consist of the following: September 30, December 31, 2018 Other Intangible Assets Gross Amortizable Asset - Customer Relationships $ 109,752 $ 109,752 Less: Accumulated Amortization - Customer Relationships 11,467 6,552 Total Other Intangible Assets, net $ 98,285 $ 103,200 During the second quarter of 2018, CNX determined that the carrying value of a portion of the customer relationship intangible assets exceeded their fair value as a result of an Asset Exchange Agreement with HG Energy. Accordingly, CNX recognized an impairment on this intangible asset of $ 18,650 . There were no such impairments in the current period. The customer relationship intangible asset is being amortized on a straight-line basis over approximately 17 years . Amortization expense related to other intangible assets for the three and nine months ended September 30, 2019 was $1,638 and $4,915 , respectively. Amortization expense related to other intangible assets was $1,638 and $5,293 for the three and nine months ended September 30, 2018 , respectively. The estimated annual amortization expense is expected to approximate $6,552 per year for each of the next five years.

Revolving Credit Facilities

Revolving Credit Facilities	9 Months Ended

Short-term Debt, Other Disclosures [Abstract]
Revolving Credit Facilities	REVOLVING CREDIT FACILITIES: CNX Resources Corporation (CNX) In April 2019, CNX amended its senior secured revolving credit facility ("Credit Facility") and extended its maturity to April 2024. The lenders' commitments remained unchanged at $ 2,100,000 , with an accordion feature that allows the Company to increase the commitments to $ 3,000,000 . The borrowing base was reaffirmed at $2,100,000 , including a $650,000 letters of credit aggregate sub-limit. In addition, the Cumulative Credit Basket for dividends and distributions was replaced with a basket for dividends and distributions subject to a pro forma net leverage ratio of at least 3.00 to 1.00 and availability under the credit facility of at least 15% of the aggregate commitments. If the aggregate principal amount of the existing 5.875% Senior Notes due in April 2022 and certain other publicly traded debt securities outstanding 91 days prior to the earliest maturity of such debt (the "Springing Maturity Date") is greater than $ 500,000 , then the Credit Facility will mature on the Springing Maturity Date. In October 2019, as part of the semi-annual borrowing base redetermination the lenders' increased CNX's borrowing base to $ 2,300,000 . Under the terms of the amended agreement, borrowings under the revolving credit facility will bear interest at CNX's option at either: • the base rate, which is the highest of (i) the federal funds open rate plus 0.50% , (ii) PNC Bank, N.A.’s prime rate, or (iii) the one-month LIBOR rate plus 1.0% , in each case, plus a margin ranging from 0.25% to 1.25% ; or • the LIBOR rate, which is the LIBOR rate plus a margin ranging from 1.25% to 2.25% . The CNX Credit Facility is secured by substantially all of the assets of CNX and certain of its subsidiaries (excluding the Excluded Subsidiaries, which includes CNX Midstream GP LLC and its subsidiaries). Fees and interest rate spreads are based on the percentage of facility utilization, measured quarterly. Availability under the Credit Facility is limited to a borrowing base, which is determined by the lenders' syndication agent and approved by the required number of lenders in good faith by calculating a value of CNX's proved natural gas reserves. The CNX Credit Facility contains a number of affirmative and negative covenants including those that, except in certain circumstances, limit the Company and the subsidiary guarantors' ability to create, incur, assume or suffer to exist indebtedness, create or permit to exist liens on properties, dispose of assets, make investments, purchase or redeem CNX common stock, pay dividends, merge with another corporation and amend the senior unsecured notes. The Company must also mortgage 80% of the value of its proved reserves and 80% of the value of its proved developed producing reserves, in each case, which are included in the borrowing base, maintain applicable deposit, securities and commodities accounts with the lenders or affiliates thereof, and enter into control agreements with respect to such applicable accounts. The CNX Credit Facility contains customary events of default, including, but not limited to, a cross-default to certain other debt, breaches of representations and warranties, change of control events and breaches of covenants. The CNX Credit Facility also requires that CNX maintain a maximum net leverage ratio of no greater than 4.00 to 1.00, which is calculated as the ratio of debt less cash on hand to consolidated EBITDA, measured quarterly. CNX must also maintain a minimum current ratio of no less than 1.00 to 1.00, which is calculated as the ratio of current assets, plus revolver availability, to current liabilities, excluding borrowings under the revolver, measured quarterly. The calculation of all of the ratios exclude CNXM. CNX was in compliance with all financial covenants as of September 30, 2019 . At September 30, 2019 , the CNX Credit Facility had $ 613,200 of borrowings outstanding and $ 199,066 of letters of credit outstanding, leaving $ 1,287,734 of unused capacity. At December 31, 2018 , the CNX Credit Facility had $ 612,000 of borrowings outstanding and $ 198,396 of letters of credit outstanding, leaving $ 1,289,604 of unused capacity. CNX Midstream Partners LP (CNXM) In April 2019, CNXM amended its senior secured revolving credit facility and extended its maturity to April 2024. The lenders’ commitments remained unchanged at $600,000 , with an accordion feature that allows CNXM to increase the available borrowings by up to an additional $250,000 under certain terms and conditions. Among other things, the revolving credit facility now includes (i) the addition of a restricted payment basket permitting cash repurchases of Incentive Distribution Rights (IDRs) subject to a pro forma secured leverage ratio of 3.00 to 1.00, a pro forma total leverage ratio of 4.00 to 1.00 and pro forma availability of 20% of commitments and (ii) a restricted payment basket for the repurchase of LP units not to exceed Available Cash (as defined in the partnership agreement) in any quarter, of up to $150,000 per year and up to $200,000 during the life of the facility. Under the terms of the amended agreement, borrowings under the revolving credit facility will bear interest at CNXM's option at either: • the base rate, which is the highest of (i) the federal funds open rate plus 0.50% , (ii) PNC Bank, N.A.’s prime rate, or (iii) the one-month LIBOR rate plus 1.0% , in each case, plus a margin ranging from 0.50% to 1.50% ; or • the LIBOR rate, plus a margin ranging from 1.50% to 2.50% . Fees and interest rate spreads under the CNXM credit facility are based on the total leverage ratio, measured quarterly. The CNXM credit facility includes the ability to issue letters of credit up to $100,000 in the aggregate. The CNXM revolving credit facility contains a number of affirmative and negative covenants that include, among others, covenants that, except in certain circumstances, restrict the ability of CNXM, its subsidiary guarantors and certain of its non-guarantor, non-wholly-owned subsidiaries, except in certain circumstances, to: (i) create, incur, assume or suffer to exist indebtedness; (ii) create or permit to exist liens on their properties; (iii) prepay certain indebtedness unless there is no default or event of default under the revolving facility; (iv) make or pay any dividends or distributions in excess of certain amounts; (v) merge with or into another person, liquidate or dissolve; or acquire all or substantially all of the assets of any going concern or going line of business or acquire all or a substantial portion of another person’s assets; (vi) make particular investments and loans; (vii) sell, transfer, convey, assign or dispose of its assets or properties other than in the ordinary course of business and other select instances; (viii) deal with any affiliate except in the ordinary course of business on terms no less favorable to CNXM than it would otherwise receive in an arm’s length transaction; and (ix) amend in any material manner its certificate of incorporation, bylaws, or other organizational documents without giving prior notice to the lenders and, in some cases, obtaining the consent of the lenders. In addition, CNXM is obligated to maintain at the end of each fiscal quarter (w) for so long as at least $150,000 of the CNXM senior notes are outstanding, a maximum total leverage ratio of no greater than 5.25 to 1.00 (which increases to no greater than 5.50 to 1.00 during qualifying acquisition periods); (x) if less than $150,000 of the CNXM senior notes are outstanding, a maximum total leverage ratio of no greater than 4.75 to 1.00 (which increases to no greater than 5.25 to 1.00 during qualifying acquisition periods); (y) a maximum secured leverage ratio of no greater than 3.50 to 1.00 and (z) a minimum interest coverage ratio of no less than 2.50 to 1.00 . CNXM was in compliance with all financial covenants as of September 30, 2019 . The CNXM revolving credit facility also contains customary events of default, including, but not limited to, a cross-default to certain other debt, breaches of representations and warranties, change of control events and breaches of covenants. The obligations under the revolving credit facility are secured by substantially all of the assets of CNXM and its wholly-owned subsidiaries. CNX is not a guarantor under the revolving credit facility. At September 30, 2019 , the CNXM credit facility had $246,000 of borrowings outstanding. CNXM had the maximum amount of revolving credit available for borrowing at September 30, 2019 , or $354,000 . At December 31, 2018 , the CNXM credit facility had $84,000

Leases [Abstract]
Leases	LEASES: On January 1, 2019, the Company adopted Accounting Standard Update (ASU) 2016-02, and all related amendments, using the transition method, which allows for a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. CNX elected the transition relief package of practical expedients by applying previous accounting conclusions under ASC 840 to all leases that existed prior to the transition date. As a result, CNX did not reassess 1) whether existing or expired contracts contain leases, 2) lease classification for any existing or expired leases or 3) whether lease origination costs qualified as initial direct costs. Additionally, the Company elected the short-term practical expedient for all asset classes by establishing an accounting policy to exclude leases with a term of 12 months or less. CNX will not separate lease components from non-lease components for any asset class. Lastly, CNX adopted the easement practical expedient, which allows the Company to apply ASC 842 prospectively to land easements after the adoption date. Easements that existed or expired prior to the adoption date that were not previously assessed under ASC 840 will not be reassessed. CNX's leasing activities primarily consist of operating and finance leases for electric fracturing equipment, natural gas drilling rigs, CNX's corporate headquarters as well as field offices, a natural gas gathering pipeline and commercial vehicles. Some leases include options to renew ranging from a period of 1 to 10 years , which are not recognized as part of the lease right-of-use (ROU) assets or liabilities as they are not reasonably certain to be exercised. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of the lease payments over the lease term. As most of CNX's leases do not provide an implicit rate, an incremental borrowing rate is used to determine the present value of lease payments. The components of lease cost were as follows: For the Three Months Ended For the Nine Months Ended September 30, 2019 September 30, 2019 Operating Lease Cost $ 21,723 $ 53,080 Finance Lease Cost: Amortization of Right-of-Use Assets 1,310 3,936 Interest on Lease Liabilities 298 974 Short-term Lease Cost 555 4,922 Variable Lease Cost* 5,015 16,554 Total Lease Cost $ 28,901 $ 79,466 *Amounts recognized on the balance sheet for natural gas drilling rigs are measured using the rates that would be paid if the rigs were idle, as this represents the minimum payment that could be made under the contract. Variable lease cost represents amounts paid for natural gas drilling rigs above this minimum when the rigs are in use. Amounts recognized on the balance sheet for electric fracturing equipment are measured using minimum pumping hours under the contract; however, pumping hours may exceed the minimum and vary period to period. Any such amounts paid related to pumping hours in excess of the minimum represent variable lease cost.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	COMMITMENTS AND CONTINGENT LIABILITIES: CNX and its subsidiaries are subject to various lawsuits and claims with respect to such matters as personal injury, royalty accounting, damage to property, climate change, governmental regulations including environmental violations and remediation, employment and contract disputes and other claims and actions arising out of the normal course of business. CNX accrues the estimated loss for these lawsuits and claims when the loss is probable and can be estimated. The Company's current estimated accruals related to these pending claims, individually and in the aggregate, are immaterial to the financial position, results of operations or cash flows of CNX. It is possible that the aggregate loss in the future with respect to these lawsuits and claims could ultimately be material to the financial position, results of operations or cash flows of CNX; however, such amounts cannot be reasonably estimated. At September 30, 2019 , CNX has provided the following financial guarantees, unconditional purchase obligations, and letters of credit to certain third-parties as described by major category in the following tables. These amounts represent the maximum potential of total future payments that the Company could be required to make under these instruments. These amounts have not been reduced for potential recoveries under recourse or collateralization provisions. Generally, recoveries under reclamation bonds would be limited to the extent of the work performed at the time of the default. No amounts related to these unconditional purchase obligations and letters of credit are recorded as liabilities in the financial statements. CNX management believes that the commitments in the following table will expire without being funded, and therefore will not have a material adverse effect on financial condition. Amount of Commitment Expiration Per Period Total Amounts Committed Less Than 1 Year 1-3 Years 3-5 Years Beyond 5 Years Letters of Credit: Firm Transportation $ 198,316 $ 80,244 $ 118,072 $ — $ — Other 750 750 — — — Total Letters of Credit 199,066 80,994 118,072 — — Surety Bonds: Employee-Related 1,850 — 1,850 — — Environmental 11,283 11,073 210 — — Financial Guarantees 81,670 26,400 55,270 — — Other 9,306 8,433 873 — — Total Surety Bonds 104,109 45,906 58,203 — — Total Commitments $ 303,175 $ 126,900 $ 176,275 $ — $ — Excluded from the above table are commitments and guarantees entered into in conjunction with the spin-off of the Company's coal business (See CNX's 2018 Annual Report on Form 10-K as filed with the SEC on February 7, 2019 for further information). Although CONSOL Energy has agreed to indemnify CNX to the extent that CNX would be called upon to pay any of these liabilities, there is no assurance that CONSOL Energy will satisfy its obligations to indemnify CNX in the event that CNX is so called upon. CNX enters into long-term unconditional purchase obligations to procure major equipment purchases, natural gas firm transportation, gas drilling services and other operating goods and services. These purchase obligations are not recorded in the Consolidated Balance Sheets. As of September 30, 2019 , the purchase obligations for each of the next five years and beyond were as follows: Obligations Due Amount Less than 1 year $ 252,535 1 - 3 years 489,023 3 - 5 years 412,960 More than 5 years 1,113,008 Total Purchase Obligations $ 2,267,526

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	DERIVATIVE INSTRUMENTS: In June 2019, CNX entered into an interest rate swap agreement to manage its exposure to interest rate volatility. The interest rate swap agreement relates to $160,000 of borrowings under CNX’s senior secured revolving credit facility (See Note 9 - Revolving Credit Facilities) and has the economic effect of modifying the variable-interest obligation into a fixed-interest obligation over a three-year period. The change in fair value of the interest rate swap agreement is accounted for on a mark-to-market basis with changes in fair value recorded in current period earnings. The fair value at September 30, 2019 and the corresponding change in fair value from inception through September 30, 2019 was nominal. CNX enters into financial derivative instruments to manage its exposure to commodity price volatility. These natural gas commodity hedges are accounted for on a mark-to-market basis with changes in fair value recorded in current period earnings. CNX is exposed to credit risk in the event of non-performance by counterparties. The creditworthiness of counterparties is subject to continuing review. The Company has not experienced any issues of non-performance by derivative counterparties. None of the Company's counterparty master agreements currently require CNX to post collateral for any of its positions. However, as stated in the counterparty master agreements, if CNX's obligations with one of its counterparties cease to be secured on the same basis as similar obligations with the other lenders under the credit facility, CNX would have to post collateral for instruments in a liability position in excess of defined thresholds. All of the Company's derivative instruments are subject to master netting arrangements with our counterparties. CNX recognizes all financial derivative instruments as either assets or liabilities at fair value in the Consolidated Balance Sheets on a gross basis. Each of the Company's counterparty master agreements allows, in the event of default, the ability to elect early termination of outstanding contracts. If early termination is elected, CNX and the applicable counterparty would net settle all open hedge positions. The total notional amounts of production of CNX's derivative instruments were as follows: September 30, December 31, Forecasted to 2019 2018 Settle Through Natural Gas Commodity Swaps (Bcf) 1,502.4 1,484.4 2024 Natural Gas Basis Swaps (Bcf) 1,240.5 1,056.6 2024 The gross fair value of CNX's derivative instruments was as follows: Asset Derivative Instruments Liability Derivative Instruments September 30, December 31, September 30, December 31, 2019 2018 2019 2018 Commodity Swaps: Prepaid Expense $ 172,836 $ 28,612 Other Accrued Liabilities $ 1,389 $ 34,640 Other Assets 254,967 164,310 Other Liabilities 17,440 52,011 Total Asset $ 427,803 $ 192,922 Total Liability $ 18,829 $ 86,651 Basis Only Swaps: Prepaid Expense $ 25,420 $ 11,628 Other Accrued Liabilities $ 43,437 $ 27,021 Other Assets 20,925 48,788 Other Liabilities 98,638 40,210 Total Asset $ 46,345 $ 60,416 Total Liability $ 142,075 $ 67,231 The effect of derivative instruments on the Company's Consolidated Statements of Income was as follows: For the Three Months Ended For the Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Cash Received (Paid) in Settlement of Commodity Derivative Instruments: Natural Gas: Commodity Swaps $ 61,441 $ 6,916 $ 53,058 $ 23,540 Basis Swaps (4,400 ) (4,091 ) (26,727 ) (21,022 ) Total Cash Received in Settlement of Commodity Derivative Instruments 57,041 2,825 26,331 2,518 Unrealized Gain (Loss) on Commodity Derivative Instruments: Natural Gas: Commodity Swaps 126,617 27,749 302,701 76,999 Basis Swaps 30,255 (12,569 ) (88,914 ) (765 ) Total Unrealized Gain on Commodity Derivative Instruments 156,872 15,180 213,787 76,234 Gain (Loss) on Commodity Derivative Instruments: Natural Gas: Commodity Swaps 188,058 34,665 355,759 100,539 Basis Swaps 25,855 (16,660 ) (115,641 ) (21,787 ) Total Gain on Commodity Derivative Instruments $ 213,913 $ 18,005 $ 240,118 $ 78,752 The Company also enters into fixed price natural gas sales agreements that are satisfied by physical delivery.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS: CNX determines the fair value of assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources (including NYMEX forward curves, LIBOR-based discount rates and basis forward curves), while unobservable inputs reflect the Company's own assumptions of what market participants would use. The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below: Level 1 - Quoted prices for identical instruments in active markets. Level 2 - The fair value of the assets and liabilities included in Level 2 are based on standard industry income approach models that use significant observable inputs, including NYMEX forward curves, LIBOR-based discount rates and basis forward curves. Level 3 - Unobservable inputs significant to the fair value measurement supported by little or no market activity. In those cases when the inputs used to measure fair value meet the definition of more than one level of the fair value hierarchy, the lowest level input that is significant to the fair value measurement in its totality determines the applicable level in the fair value hierarchy. The financial instrument measured at fair value on a recurring basis is summarized below: Fair Value Measurements at September 30, 2019 Fair Value Measurements at December 31, 2018 Description (Level 1) (Level 2) (Level 3) (Level 1) (Level 2) (Level 3) Gas Derivatives $ — $ 313,244 $ — $ — $ 99,456 $ — The carrying amounts and fair values of financial instruments for which the fair value option was not elected are as follows: September 30, 2019 December 31, 2018 Carrying Amount Fair Value Carrying Amount Fair Value Cash and Cash Equivalents $ 5,484 $ 5,484 $ 17,198 $ 17,198 Long-Term Debt (Excluding Debt Issuance Costs) $ 2,649,802 $ 2,505,114 $ 2,387,001 $ 2,290,537 Cash and cash equivalents represent highly- liquid instruments and constitute Level 1 fair value measurements. Certain of the Company’s debt is actively traded on a public market and, as a result, constitute Level 1 fair value measurements. The portion of the Company’s debt obligations that is not actively traded is valued through reference to the applicable underlying benchmark rate and, as a result, constitute Level 2 fair value measurements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	VARIABLE INTEREST ENTITIES: The Company determined CNXM, of which the Company owns an approximately 34% limited partner interest and 100% of the general partner interest, to be a variable interest entity. As a result of the Midstream Acquisition (see Note 5 - Acquisitions and Dispositions), the Company has the power through the Company's ownership and control of CNXM's general partner (CNX Midstream GP LLC) to direct the activities that most significantly impact CNXM's economic performance. In addition, through its limited partner interest and incentive distribution rights, or IDRs, in CNXM, the Company has the obligation to absorb the losses of CNXM and the right to receive benefits in accordance with such interests. As the Company has a controlling financial interest and is the primary beneficiary of CNXM, the Company consolidated CNXM commencing January 3, 2018. The risks associated with the operations of CNXM are discussed in its Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on February 7, 2019 and its other periodic reports filed after that date. The following table presents amounts included in the Company's Consolidated Balance Sheets that were for the use or obligation of CNXM: September 30, December 31, 2019 2018 Assets: Cash $ 1,735 $ 3,966 Receivables - Related Party 17,845 17,073 Receivables - Third Party 6,074 7,028 Other Current Assets 1,646 2,383 Property, Plant and Equipment, net 1,144,177 891,775 Operating Lease ROU Asset 6,281 — Other Assets 3,508 3,203 Total Assets $ 1,181,266 $ 925,428 Liabilities: Accounts Payable and Accrued Liabilities $ 99,118 $ 43,919 Accounts Payable - Related Party 3,788 4,980 Revolving Credit Facility 246,000 84,000 Long-Term Debt 393,925 393,215 Long-Term Operating Lease Liabilities 40 — Total Liabilities $ 742,871 $ 526,114 The following table summarizes CNXM's Consolidated Statements of Operations and Cash Flows, inclusive of affiliate amounts: For the Three Months Ended September 30, For the Nine Months Ended September 30, 2019 2018 2019 2018 Revenue Gathering Revenue - Related Party $ 55,453 $ 41,022 $ 168,434 $ 116,328 Gathering Revenue - Third Party 18,523 19,946 55,862 69,523 Total Revenue 73,976 60,968 224,296 185,851 Expenses Operating Expense - Related Party 6,105 5,131 18,167 14,645 Operating Expense - Third Party 5,612 4,870 17,774 20,744 General and Administrative Expense - Related Party 3,573 3,060 11,567 10,292 General and Administrative Expense - Third Party 1,236 1,771 4,136 6,639 Loss on Asset Sales and Abandonments — — 7,229 2,501 Depreciation Expense 6,184 5,306 17,694 16,605 Interest Expense 7,601 7,255 22,625 16,863 Total Expense 30,311 27,393 99,192 88,289 Net Income $ 43,665 $ 33,575 $ 125,104 $ 97,562 Net Cash Provided by Operating Activities $ 51,014 $ 35,666 $ 175,680 $ 131,207 Net Cash Used in Investing Activities $ (68,289 ) $ (44,241 ) $ (251,156 ) $ (79,366 ) Net Cash Provided by (Used in) Financing Activities $ 7,333 $ 8,818 $ 73,245 $ (54,085 ) In March 2018, CNXM closed on its acquisition of CNX's remaining 95% interest in the gathering system and related assets commonly referred to as the Shirley-Penns System, in exchange for cash consideration in the amount of $265,000 . CNXM funded the cash consideration with proceeds from the issuance of its 6.50% senior notes due 2026 (See Note 11 - Long-Term Debt). At September 30, 2019 and December 31, 2018 , CNX had a net payable of $ 14,085 and $ 12,202

Segment Information

Segment Reporting [Abstract]
Segment Information	SEGMENT INFORMATION: CNX consists of two principal business divisions: Exploration and Production (E&P) and Midstream. The principal activity of the E&P Division, which includes four reportable segments, is to produce pipeline quality natural gas for sale primarily to gas wholesalers. The E&P Division's reportable segments are Marcellus Shale, Utica Shale, Coalbed Methane, and Other Gas. The Other Gas Segment is primarily related to shallow oil and gas production which is not significant to the Company due to the sale of substantially all of CNX's shallow oil and gas assets in the 2018 period (See Note 5 - Acquisitions and Dispositions for more information). It also includes the Company's purchased gas activities, unrealized gain or loss on commodity derivative instruments, exploration and production related other costs, as well as various other operating activities assigned to the E&P Division but not allocated to each individual segment. CNX's Midstream Division's principal activity is the ownership, operation, development and acquisition of natural gas gathering and other midstream energy assets of CNX Gathering and CNXM, which provide natural gas gathering services for the Company's produced gas, as well as for other independent third-parties in the Marcellus Shale and Utica Shale in Pennsylvania and West Virginia. Excluded from the Midstream Division are the gathering assets and operations of CNX that have not been contributed to CNX Gathering and CNXM. As a result of the Midstream Acquisition (See Note 5 - Acquisitions and Dispositions for more information), CNX owns and controls 100% of CNX Gathering, making CNXM a single-sponsor master limited partnership and thus the Company began consolidating CNXM on January 3, 2018. The Company's unallocated expenses include other expense, gain on asset sales related to non-core assets, gain on previously held equity interest, loss on debt extinguishment, impairment of other intangible assets and income taxes. In the preparation of the following information, intersegment sales have been recorded at amounts approximating market prices. Operating profit for each segment is based on sales less identifiable operating and non-operating expenses. Assets are reflected at the division level for E&P and are not allocated between each individual E&P segment. These assets are not allocated to each individual segment due to the diverse asset base controlled by CNX, whereby each individual asset may service more than one segment within the division.

Stock Repurchase [Abstract]
Stock Repurchase	STOCK REPURCHASE: Since the October 30, 2017 inception of the current stock repurchase program, CNX's Board of Directors has approved in total a $750,000 stock repurchase program, which is not subject to an expiration date. The repurchases may be affected from time-to-time through open market purchases, privately negotiated transactions, Rule 10b5-1 plans, accelerated stock repurchases, block trades, derivative contracts or otherwise in compliance with Rule 10b-18. The timing of any repurchases will be based on a number of factors, including available liquidity, the Company's stock price, the Company's financial outlook, and alternative investment options. The stock repurchase program does not obligate the Company to repurchase any dollar amount or number of shares and the Board may modify, suspend, or discontinue its authorization of the program at any time. The Board of Directors will continue to evaluate the size of the stock repurchase program based on CNX's free cash flow position, leverage ratio, and capital plans. During the nine months ended September 30, 2019 , 12,929,487 shares were repurchased and retired at an average price of $ 8.91 per share for a total cost of $115,477 .

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS: In May 2019, the FASB issued ASU 2019-05 - Financial Instruments - Credit Losses (Topic 326), which provides optional targeted transition relief to entities adopting ASU 2016-13. ASU 2016-13 replaces the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The measurement of expected credit losses will be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. ASU 2019-05 provides the option to irrevocably elect the fair value option for certain financial assets previously measured at amortized cost basis. For those entities, the targeted transition relief will increase comparability of financial statement information by providing an option to align measurement methodologies for similar financial assets. The amendments in this ASU will be applied using the modified-retrospective approach and, for public entities, are effective for fiscal years beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's financial statements.
